In this study, a thermal treatment method for poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) films on glass substrate was treated by a pulsed CO₂ laser in the atmospheric environment. The two main parameters of the PEDOT: PSS films in thermal treatment are laser fluence and scan speed. The electrical, optical, and surface properties were measured by an in-line four-point probe instrument, spectrophotometry, atomic force microscope (AFM), scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS). After treatment, the conductivity was enhanced from 2.83E-02 S/cm to 59.4 S/cm in 181 s due to removing the residual water in the film. Furthermore, the transmittance value was decreased from 89.1% to 88.5%, and the surface roughness increased from 2.27 to 2.49 nm. The conductivity increased due to the reunion between PEDOT: PSS molecules and increased in the surface PEDOT/PSS ratio. However, when the laser power exceeded the durability of the PEDOT: PSS, a significant decrease in conductivity and transmittance was observed. Compared with the hotplate thermal treatment in the atmospheric environment, CO₂ pulsed laser thermal treatment has advantages for PEDOT: PSS thermal treatment in a small region.

在这项研究中，通过脉冲CO ₂处理玻璃基板上的聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）薄膜的热处理方法大气环境中的激光。PEDOT的两个主要参数：热处理中的PSS膜是激光通量和扫描速度。通过在线四点探针仪，分光光度法，原子力显微镜（AFM），扫描电子显微镜（SEM）和X射线光电子能谱（XPS）测量电，光学和表面性能。处理后，由于去除了薄膜中的残留水，电导率在181 s内从2.83E-02 S / cm提高到59.4 S / cm。此外，透射率值从89.1％降低到88.5％，并且表面粗糙度从2.27nm增加到2.49nm。电导率由于PEDOT：PSS分子之间的团聚而增加，并且表面PEDOT / PSS之比增加。但是，当激光功率超过PEDOT：PSS的耐用性时，观察到电导率和透射率显着降低。与大气环境中的热板热处理相比，CO₂脉冲激光热处理对于PEDOT具有优势：PSS热处理在小范围内。
